I like WD and have had no issues (now where is that wood.)
The last Seagate I had issues with was a 46MB, yes, MEGA Byte. I learned what stiction was with that one (MFM? - it was in an AT). In the pools of them I have seen recently, they have been reliable.
From the server realm, I learned how to spell stiction from IBM. Will never recommend IBM drives (now owned by Hitachi). More than 50% of the 10GB EIDEs, I know of, lost track 0 from year 2-5. Yuck.
Maxtor - I have seen one minor and one significant firmware issue with Maxtors. The minor was resolved with changing jumpers for CS to MS/SL. The other one, I cannot discuss, but it is not anything you would buy. But otherwise, they have been good (about 10000).
Last WD issue I remember was a 4 platter drive about 10-12 years ago. I thought it was 160MB, but it has been a freaking long time.
